JOSEPH C. HARTMAN, OF COLLINWOOD, OHIO.

RAILWAY DRAFT DEVICE.

To all whom it may concern:

Be it known that I, Josnri-i O. HARTMAN, a citizen of the United States,residing at Collinwood, in the county of Cuyahoga and State of Ohio,have invented a new and usefulRailway Draft Device, of which thefollowing is a specification.

This invention relates to car couplers of the Janney type, and has forits object the provision of a draw head capable of swinging laterally toconform with the relative lateral movement of coupled cars.

Another object is to simplify and otherwise improve upon devices of thischaracter without diminishing their strength or efficiency.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings, the preferred form of the invention hasbeen shown.

In said drawings: Figure 1 is a plan view of the car coupler a portionof the draw head being broken away. Fig 2 is a central verticallongitudinal section through the coupler. Fig. 3 is a perspective viewof the draw head. Fig. 4t is a perspective view of the knuckle.

Referring to the figures by characters of reference, 11 designates adraw bar adapted to be connected to a car structure in any preferredmanner.

The front end of the drawbar 11 is formed with a head 24, having a pairof spaced forwardly-projecting horns 25 between which is a web 26, towhich the draw head 27 of the coupler is pivoted. The draw head issimilar in contour to an ordinary J anney draw head, there being aforwardlyprojecting horn or guard arm 28 at one side, and two spacedforwardly-projecting ears 29 on the opposite side, between which earsthe knuckle 30 is pivoted by a pin 31. The rear Specification of LettersPatent.

Serial No. 520,307.

end of the draw head is formed with spaced ears 30 extending between thehorns 25, and bet-ween which ears the web 26 is received, a pivot pin 32passing through the ears and the web. The knuckle 30 has a projectingtail piece 33 which is engageable by a coupling pin 34 passing throughalined openings in the ears 29, for locking the knuckle in closedposition. In looking position the pin extends in front of the tailpiece, which prevents the knuckle from swinging to open position.

At 36 is indicated a coiled spring which automatically throws theknuckle to open position when released by the coupling pin 34. One endof this spring is connected to the tail piece of the knuckle and theother end to the head 24:.

The coupler herein described is simple in structure, and reliable inoperation, and can be readily locked and unlocked. The pivot 32 isvertical so that the drawhead is free to swing in a horizontal planelaterally, and thus follow a corresponding movement of the car, as whengoing around a curve, without any danger of uncoupling or strain oncylinder or piston rod.

WVhat is claimed is The combination with a draw bar having a head at oneend, and oppositely disposed curved horns extending from the head andhaving a substantially horizontal web therebetween, of a draw head aguide arm extending forwardly from one side portion of the draw head,there being a substantially horizontal slot extending into the draw headfrom the other sidethereof and terminating within the guide arm, therebeing upper and lower arcuate ears at one side of the draw head andhaving alining apertures, and upper and lower rearwardly extending earsfor the reception of the said web there between, a pivot pin within saidapertures in the rearwardly extending ears and engaging the web, aknuckle pivotally mounted between the forwardly extending arcuate earsand having a tail piece movable within the slot, a spring connectionbetween said tail piece and the guide arm, and a coupling pin movablymounted within the registering apertures in the arcuate ears and adaptedIn testimony that I claim the foregoing to be supported 1n lEIlSQClpositlon by the as my own, I have hereto affixed my slgnatall piece,said pin being movable clownture 1n the presence of two witnesses.

Warclly by gravity upon the removal of the JOSEPH C. HARTh/IAN. tailpiece thereunder, to lock the knuckle in WVitnesses:

closed position and with the spring under R. MAX SoLYMoN,
